I imported the sites for your trunked systems, based on the counties where you imported talkgroups.
See if this revised file works for you. I see that you have Hudson talkgroups downloaded for the state system, NJICS, but there does not show to be a site specifically in that county. So I made sure that sites from the counties adjacent to Hudson were imported. I did not assign quick keys to any of the sites. You, of course, can use them, or skip that step & let the scanner monitor all of the sites.
For Bergen, their system shows 3 sites: a North and a South Uhf Simulcast, and a 700 MHz simulcast. Somebody in your area, if you have your thread moved to your state forum, would be able to advise you which one (or more than one) site that you need.
Also, most of these sites are simulcast, which can cause problems for scanners other than Uniden's SDS series. This
Wiki article describes those problems, and offers a few suggestions that might help, though there is no guarantee. Sometimes, something as simple as repositioning the scanner a foot or two can make a big difference.
